Good point! I checked their schedule. Bayern 1 wouldn't have been on Die Nacht at this time on a Sunday evening, so definitely Bayern 1 from Reit im Winkl. As it happens, I found a panoramic view of Reit Im Winkl on YouTube. What a beautiful place! https://www.youtube.com/watch?v=5PQ_s5cjdhE

yes nice little village near the border to Tyrol (Kössen). they have excellent winter sport areas on several mountain's tops over there (Steinplatte Waidring, Hochkössen, Ruhpolding...). some famous folk music singer (Maria and Margot Hellwig) were born over there.
